Claims

[Scope of utility model registration request]

In a cylinder device consisting of a piston rod and a piston that are inserted into the cylinder from one end side under an airtight or liquid-tight seal and can slide inside the cylinder, the piston rod is fixed to an end portion of the cylinder and the piston rod is slidably movable inside the cylinder. The wall thickness of the cylinder mounting portion corresponding to the portion where the end cover member, which can be freely inserted and removed under airtight or liquid-tight sealing, is located is made larger than the wall thickness of the cylinder wall portion corresponding to the piston sliding portion. A cylinder device having different diameter cross sections.
